Wait and See?

A Reddit user posted an image asking, "Is it yeast or mould?" with a kombucha brew showing a few early-stage spots that raised concerns. These types of marginal cases are common and tricky—it’s often hard to tell whether the brew is safe or if mould is developing. In situations like this, the best course of action is usually to wait and monitor the spots over time, as mould becomes more evident if given the chance to grow.

Why It Matters
Mould contamination can pose serious health risks and ruin an entire batch of kombucha. However, spotting mould at its early stages can be difficult, especially when the signs are subtle or borderline. This case underscores a frequent issue for home brewers: it’s easy to overreact and throw out a batch prematurely, but it’s equally risky to let potential mould grow undetected. Many brewers seek advice on community forums, but responses can be inconsistent or even misleading. What looks like mould to one person might be dismissed as yeast by another, leaving brewers unsure of how to proceed. That’s why a “wait and see” approach is recommended in this case, allowing enough time to see if the suspicious spots develop into something more concerning.
